Police are investigating a collision between Labour leader Sir Keir Starmer’s car and a cyclist, who was taken to hospital with injuries.
Sir Keir was driving through northwest London at about midday on Sunday when the crash occurred in Kentish Town.
A spokesman for the opposition leader said he swapped details with the cyclist and waited for an ambulance to arrive before later reporting the incident to police.
The cyclist was treated for a minor injury to his arm and taken to hospital as a precautionary measure.
A spokesman for the Labour leader said: “Keir was involved in a minor road traffic accident on Sunday. He spoke to a British Transport Police officer who attended the scene and swapped details with the officer and the other individual involved.
“Keir stayed at the scene until the ambulance arrived. Later that afternoon, he reported the incident to a police station in accordance with the law.
“Since the incident, Keir has also been in touch with the other individual involved.”
The Sun newspaper quoted a witness, IT developer Nicolas Janes, 39, who said he had heard a "loud bang" and saw a cyclist on the pavement who appeared to be in a "lot of pain".
A Metropolitan police spokesperson confirmed the driver involved in the collision was not arrested and has not been interviewed under caution.
They added: “Police were alerted by [London Ambulance Service] at around 12.20hrs on Sunday 25 October to a report of a road traffic collision between a cyclist and car in Grafton Road, NW5.
“The driver of the car had stopped at the scene and exchanged details with the cyclist but had left before officers arrived.
“The male cyclist received a minor injury to his arm and was taken to hospital by LAS as a precaution.

“The driver of the car subsequently attended a north London police station. He was not arrested or interviewed under caution.
